st,stm32-rng

Description

STM32 Random Number Generator

Properties

Properties not inherited from the base binding file.

Name

Type

Details

nist-config

int

This property is used to configure the RNG_CR for the NIST certification
The validation conditions are following the refMan
to certify NIST SP800-90B. RNG clock source must be 48MHz.
This config is valid with some STM32 families
and when Conditioning Soft Reset (RNG_CR_CONDRST bit) exists.
The value is directly mapped from the RNG configuration (A) table.
The Health Register (health-test-config property) must correspond
to this table configuration.
On the stm32U5, the ARDIS bit7 is also written.

health-test-magic

int

Magic Number to be written to Health Test Configuration Register (HTCR)
prior to real configuration, if any.

health-test-config

int

Heath Test Configuration, necessary to have proper RNG behavior,
when available.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “st,stm32-rng” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information This property is required.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.
`power-domain`	`phandle`	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
